ROTARY ENGINE,

SPECIFICATION forming part of Letters Patent No. 650,214, dated May 2 2, 1900.

Application filed september 14, 1899- Serlal No. 730,492. (No model.)

To all whom it may concern: Be it known that I, JOHN J. ANTHONY, of

Moscow, in the county of Latah and State of' Idaho, have invented a new and Improved RotaryEngine, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved rotary engine which is simple, durable, and compactin construction, very effective in operation, easily cared for and manipulated, and arranged to reduce friction to a minimum and to utilize the motive agent expansively and to the fullest advantage and with the greatest economy.

represented in the accompanying drawings,

forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views. a

Figure 1 is a cross-section of the improvement on the line 11 in Fig. 2.- Fig. 2 is a sectional plan view of the same on the line 2 2 in Fig. 1. Fig. 3 isa sectional side elevation of the same on the line? 3 in Fig. 1. Fig. 4 is a similar view of the same on the line 4 4 in Fig. 1. Fig. 5 is a cross-section of the same on the line 5 5 in Fig. 2. Fig. 6 is aplan view of part of the improvement, showing more particularly the connection between the govcrnorand the cut-01f valve; and Fig. 7is a perspective view of one of the abutments.

The improved engine is provided with a cylinder A, having heads A A and in which is mounted to rotate a piston B, secured on a shaft- C, mounted to trim in roller-bearings D, having their external casing D secured in the cylinder-heads A A and in the chests E E, secured to the cylinder-heads A A respectively. vided with a plurality of piston-heads B B extending to the inner peripheral surface of the cylinder, so as to form a plurality of working chambers in the cylinder to simultaneously receive the motive agent from the two chests E E, each of which is provided with a supply pipe I, connected with a suitable source of motive-agent supply. The exhaust motive agent passes from the working cham- The invention consists of novel features- The piston B is preferably pro friction-rollers H in engagement witheam-,

grooves I, formed on cam-wheels I, secured on the piston-shaft ,0, so that the cam-wheels control the abutments. The cam-wheels may also serve as fly-wheels for the engine and as power-transmitting wheels for transmitting the rotary motion of the engine to other machinery. The cam -grooves I in the cam-' wheels I are so arranged that the abutments H H are simultaneously moved outward or inward to allow the piston heads to pass, the

inward motion being accomplished immedi-' ately after the heads have passed the abutments. The piston-flanges B B are in con tact with the inner faces of the cylinder-heads A A and in each of said flanges are formed inlet-ports a 11, preferably arranged diametrically opposite each other immediately in front of the piston-heads B B The ports a I) register with ports 0 (1, respectively, formed in each of the cylinder-heads A A and said ports are adapted to register with ports e f, respectively, formed in the cut-ofi valves J J, mounted to rotate on the ball-bearing casings D D within the chests E-E, respectively.

Each of the cut-ofi valves J with an oifsetJ formed on its peripheral surface with gear-teeth J 3 (see Fig. 5) in mesh with teeth K of a segmentalgear-wheel K, journaled at K in the corresponding chest E or E. The outerend K of each segmental gear-wheel K is formed with an elongated slot K into which projects the end of an arm I. on a crank-shaft. L, mounted to turn in' suitable bearin gs arranged on the corresponding chest E or E. Each shaft L is provided with an arm L connected by a link L (see Fig. 6) with a shifting collar N, mounted to slide on the ball-bearing casing D, and each shifting collar is engaged by a bell-crank lever N, controlled by a centrifugal governor J is provided on the corresponding cam-'wheel'I. This centrifugal governor 0 consists, essentially, of a weighted lever O'-,fu1crumed on the'camwheel land held against outward movement 02," as indicated in' dotted-"lines. n same in two sections H H,(see Fig. 7,)havy a sp in Fig. '5.

When the engine runs at a normalrate of speed, thenthe ports e f in the cut-0E valves J J'register with thecylinder-headports c d 1 and d f are in full register and theports a b but when-the engine runs 'atia higher rateof speed then the action of each centrifugal gov ernor causes a swinging of the bell-cran'k'le 'ver N',so.that the shifting collar N is moved in a longitudinal direction relatively to the shaft 0, and consequently a turning motion isgiven to the shaft L, so that the arm L thereof imparts a swinging motion to the corresponding segmental gear-wheel'K to turn the cut-0t! valve J or J and move the ports 6 f more or less out of register with the ports c d to produce the desired cut-otf and thereby admit less motive agent to the engine un-, til the latter -again runs at a normal rate of speed. When the several parts are in the position illustrated in Fig. 1 then theports c e have just moved into register with the ports 0 d, so that the motive agent from thechests E'E' can pass'i'nto the cylinder Ato press against the piston-heads B B? and rotate the piston-B in the direction of the arrow er, the

finally cut-ofi from the ports 0 d,so'that no moremotive agent isadmitted to the cylinder, and'the motive agent now in the. work-- ing=chambersworks expansively until the; piston-heads B" B uncover the exhaust-pipes v Gto allowthe exhaust motive agent to escape from the working chambers. The cylinder A is cut out atltheinner ends of the-exhaust pipesGiin the direction toward the abutinents H H so that exhaust takes place from the cylinder until the piston heads the abut-v ment and thelatter have again been moved .into an innermost position, it,.being understood that saidabutments are moved outward by the action of the cam-wheelsl immediately previous to the piston-heads coming close to said abutments. When the pistonheads have passed he abutments and the latter have moved into an innermost position, then the ports-a b begin to registerwith the.

ports d a, respectively, and motive agent is "motive. agent contained in the cylinder-to again admitted into the two working chambers to give another'impulse to thepiston B in the direction of the arrow a'--. As the pis. ton rotates the ports a I) soon out 01f on the ports (1 c to prevent further admission of mo-x tive agent to the cylinder and to allow-the work expansively on the piston-heads in the manner previously mentioned. When the piston heads finally pass the exhaust-pipes G, then exhaust'takes place, as previously described. v

In order to prevent leakage at'the registering ports, I provide the heads A A at the] ports 0 d with suitable packing-plates P, let in the cylinder-heads A"A as indicated in Fig. 3. In order to prevent leakage at the abutments, I prefer to construct each of the ing' their adjacent ends interlocked, a wedge H being-in the adjacent ends to move "the sections'H H apart in firm contact with the =inner.faces of the piston-flanges B B The wedge H7 terminates in a bolt H engaging thexcorresponding'bar H or H and serving to adjust the we'dgefor ad j usting the sections H H. The sections areuheld on tongues 11 on the insides of the ha rs I-P Hflasshown in 'Fig- 7. f
